[Mohammed Chalil]

sakthi, ISO streams doesn't have DRC. but you can use mp4mcenc source for
making DRC streams.

DAB 
uses DRC.  is to adapt the 
dynamic range of the audio signal to listening listening environment. along
with 
audio data, receiver can receive the range info and apply the DRC to
required 
level without clipping the PCM.  see AAC std and ISO ref code for 
details.
